Study summary

In this study, we aim to compare the effects of end-tidal controlled and manually controlled low-flow anesthesia on anesthetic agent consumption in elective surgeries.

Read the detailed description

In this study, we aim to compare the effects of end-tidal controlled and manually controlled low-flow anesthesia on anesthetic agent consumption in elective surgeries. This evaluation will contribute to understanding whether automated systems provide measurable advantages in clinical settings.This evaluation will contribute to understanding whether automated systems provide measurable advantages in clinical settings.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Dec 16, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
